Clip for PVC tube enclosure - holds multi layer insulation panel

These clips are fitting on 1/2" Schedule 40 PVC tube. Their purpose is to attach insulation material on an enclosure using a PVC tube frame.

Use these clips in combination with the corners I created to link each sides of the enclosure together (see my related things).

Two versions exist: one clip holding insulation material on one side, another clip holding insulation material on two faces
